Question

Quizplus · Accepted Answer

CEA (carcinoembryonic antigen) is a tumor marker that is frequently measured in patients with colorectal cancer to monitor disease progression and response to treatment. It is not used in the diagnosis of colorectal cancer, but rather to track changes in CEA levels over time. PSA (prostate-specific antigen) is a tumor marker used to monitor prostate cancer, TA-90 is not a recognized biomarker in cancer, and NSE (neuron-specific enolase) is a marker used in small cell lung cancer and neuroendocrine tumors, not colorectal cancer.
